Nuclear fission is process which heavy nucleus splits into fragments
With roughly equal mass
The energy released is KE of fragments, neutrons released can continue splitting
More nuclei, chain reaction
When the mass above critical mass
Chain reaction starts, nucleus concentrated
Einstein relativity shows mass form of energy
Mass alone is not conserved, E is mc^2 plus KE
The mass of a nucleus is less than sum of the nucleons
Energy must be released in forming the nucleus
Energy is needed to split nucleus to nucleons
This energy is called as the binding energy
Nuclear fusion is union of 2 light nuclei, forms heavy nucleus
Energy is released
High temperature needed for the reaction
Gas atom should be ionised, nuclei energy enough to overcome
The coulomb repulsion, which is utterly large
In centre of sun, it is truly satisfied
Einstein relativity shows mass form of energy
Mass alone is not conserved, E is mc^2 plus KE
The mass of a nucleus is less than sum of the nucleons
Energy must be released in forming the nucleus
Energy is needed to split nucleus to nucleons
This energy is called as the binding energy
For nuclide with mass defect delta m
Binding energy delta mc squared
Einstein relativity shows mass form of energy
Mass alone is not conserved, E is mc^2 plus KE
The mass of a nucleus is less than sum of the nucleons
Energy must be released in forming the nucleus
Comparing binding energy between two different nuclei,
There is a term we can use, binding energy per nucleus
If EBA is larger, nuclear potential lower
EBA is largest for Fe, Fe is most stable
